Nested JOINs

Hello,
I am trying to execute an SQL query that contains nested joins, but I
get parser error for some reason.
Below is the query I am trying to execute and the error I am getting:
SELECT media
FROM (dtrowmedia a INNER JOIN dtrow b ON (a.dtrow = b.objectid)) c
INNER JOIN dtcol d ON (c.dtcol = d.objectid)

psql: ERROR: parser: parse error at or near "inner"

Note that the following query executes with no errors:
SELECT media
FROM dtrowmedia a INNER JOIN dtrow b ON (a.dtrow = b.objectid)
INNER JOIN dtcol d ON (b.dtcol = d.objectid)

What am I doing wrong?
Please help me get it to work.
Thanks

Oleg
